3 Claims. (`Cl. 105--369) This invention relates to freight cars and more particularly to a combined door post and lading strap anchor and the method of forming,

the same.

An object of the invention is to provide a combined sheet metal freight car door post and interior lading strap anchor of a construction such that it will not be weakened by strap receiving openings therein.

Another object of the invention is to provide a sheet metal freight car door post and interior lading strap anchor having the rigidity and strength required for al1 operating conditions.

These and other objects of the invention will be apparent to those skilled in the art from a study of the following description and accompanying drawings, in which:

Figure 1 is a fragmentary perspective view of the interior of a freight car with lading held therein by tie straps attached to a combined door post and anchor structure.

Figure 2 is a sectional view through the door post structure taken on line 2-2 of Figure 1.

Figure 3 is a fragmentary View looking outwardly at the inside corner of the door post.

Figure 4 is a fragmentary plan View of the sheet metal post after one of the openings has straps is associated. The car includes the usual floor II and wall structures consisting of an inner board Wall I2 and an outer sheet metal wall I3. In at least one side wall structure there is an opening I4 for loading and unloading lading, such as containers I5, and the usual sliding door I6 is associated with the opening.

At at least one side of the opening is a post structure incorporating my invention and consisting generally of a U-shaped sheet metal post Il, a wooden filler I8, to which the post is secured by bolts I8, and a tacking strip 20. Door stop 2| is suitably fixed to the outer leg of the door post.

The door post is initially in the form of a rectangular flat sheet of metal, as indicated by numeral 22 in Figure 4. Longitudinally aligned I-shaped openings 23, as shown in Figure 4, are formed in the sheet preferably by a punching operation. The sheet is next bent into U-shape with the inside corner extending in alignment with the vertical portions of the openings. During this bending operation, or in a separate followingoperation, the tongues 24 are bent inwardly until their adjacent free ends are in abutting relation and in such relation theyare secured together by welding as indicated by numeral 25. These tongues are preferably curved inwardly similarly and provide concave solid braces across the openings left in the corner of the post. Rod 26 is next inserted lengthwise against the inner faces of the slotted corner of the post and is welded thereto as indicated by numeral 21.

The rod 26 is preferably of suiiicient length to extend across all of the openings and provides an anchor for straps 28. The concave braces are spaced from the rod and serve as guidescfor the lading straps while being applied to the anchors.

It will be noted that the openings in the post corner do not materially weaken the post as the rod and the flanges provide rigid braces across the openings. It will also be noted that the post and anchor structure can be readily formed and assembled without difficulty.

The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the appended claims is contemplated.

What is claimed is: I

1. In a freight car, the combination of a sheet metal U-shaped door post having openings in one corner thereof, and a lading strap anchor rod fixed in the corner of the post and extending lengthwise across the openings, the sides of said openings being spaced from said rod sulciently to provide anchor strap clearance therebetween.

2. In a freight car, the combination of a hollow door post having an opening in one corner thereof and inwardly curved brace means across the walls of the corner behind the opening, and a lading strap anchor member fixed in said corner of the post and extending lengthwise across the opening, the sides of said opening and the curved brace means being spaced from said rod suiciently to provide anchor strap clearance therebetween.

3. In a freight car, the combination of a U-shaped sheet metal door post having an opening in one corner and secured together tongues behind the opening extending inwardly of the post from the walls forming the corner, and a lading strap anchor member fixed in said post corner and extending across the opening, the sides of said opening and the tongues being spaced from the anchor member suciently to provide lading strap clearance therebetween.
